导航栏Swift中的文本颜色

Question

我想在导航栏中显示白色文字，但只要我有白色字体代码，我仍然会将其设为黑色。

    let titleDict: NSDictionary = [NSForegroundColorAttributeName: UIColor.whiteColor()]
    self.navigationController?.navigationBar.titleTextAttributes = titleDict
    self.navigationController?.navigationBar.titleTextAttributes = [ NSFontAttributeName: UIFont(name: "HelveticaNeue-Light", size: 20)]

我试过

self.navigationController？.navigationBar.titleTextAttributes = [NSFontAttributeName：UIColor.whiteColor（）]

但没有工作

Answer 1

似乎每次设置titleTextAttributes时都要覆盖更改。尝试同时设置所有属性：

self.navigationController?.navigationBar.titleTextAttributes = [        
    NSFontAttributeName: UIFont(name: "HelveticaNeue-Light", size: 20),
    NSForegroundColorAttributeName: UIColor.whiteColor()
]
